Shawn Shuoshuo Chen

I am a 5th year PhD student in the Computer Science Department at Carnegie Mellon University, co-advised by Srinivasan Seshan and Peter Steenkiste. My research aims to deliver scalable, cost- and power-efficient connectivity to networked systems. Most recently, I have been working on data center and HPC networks, optical networks, and machine learning systems.

Prior to CMU, I was a technical lead on Google’s Network Infrastructure team. I built Google’s Jupiter fabric and its SDN controller Orion.

I received my masters degree in computer engineering from University of Virginia, and a bachelor in electrical engineering from Wuhan University.

📣📣📣 I am on the tenure-track faculty job market this year.
